Server Stats

Administration → Server Stats is an admin-only page that reports what's on disk and in the catalogue.

What's shown

Top-line counts

Metric What it counts
Platforms Every platform RomM has seen at least one ROM for. Deleted platforms don't count.
Games Total ROM entries. Multi-file (folder with multiple files) and physical games count as 1.
Saves User save files across all users.
States Emulator save states across all users.
Screenshots User-uploaded screenshots. Provider-fetched screenshots aren't counted here.
Size on disk Total disk usage of all ROMs, saves, states, and screenshots.

Per-platform breakdown

Under the summary, it's a table sorted by name, size or game count. For each platform, you can see:

  • Game count
  • Size on disk (in bytes and by percentage of total)
  • Region distribution (how many games tagged USA, Japan, Europe, World, etc.)
  • Metadata coverage (how many games have metadata from each provider)

API

The same data is available programmatically:

GET /api/stats
GET /api/stats?include_platform_stats=true
Authorization: Bearer <token>

Wire to your monitoring stack via the API rather than scraping the HTML page (see the API Reference).

Troubleshooting

  • Numbers look stale: stats are computed on page load, not cached
  • Disk sizes look wrong: if your compose mounts a path that's smaller than the host dataset (e.g. you mounted a sub-directory), it will only see that subset
  • "Platform stats couldn't load": the DB query timed out on a very large library

For anything else, see Troubleshooting.
